IMPROVEMENT IN OIL-CUPS.

Specification forming part of Letters Patent No. 179,558. dated July 4,1876; application filed June 12, 1876. e

To all whom it may concern:

Be it known that I, EZRA B. HIGH, of Reading, in the county of Berks andState of Penn sylvania, have invented a new and useful Improvement inOil-Cups, of which the following is a specification:

Figure 1 is a longitudinal section of my improved oil-cup, taken throughthe line 0o 00, Fig. 2. Fig. 2 is a cross-section of the same, takenthrough the line y 3 Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved oil-cup foroiling the journals of shafts and other bearings, which shall be soconstructed as to furnish a constant and uniform supply of oil to thebearing at all times.

The invention consists in an improved oilcup formed of the reservoir,provided with a bottom, and a hollow stem closed with a screwplug, thedistributing-chamber provided with. a hollow screw-stem, and the airhole or vent, and the three tubes, said parts being constructed andarranged to operate in connection with each other, as hereinafter fullydescribed.

The oil-cup is made in two parts, A D, which are screwed together. Theupper partor reservoir A is made with a bottom, a and with a neck orhollow stem, a having a funnelshaped upper end, and having ascrew-thread cut in its inner surface to receive a screw-plug, G, sofitted as to be air-tight. The lower part or distributing-chamber Dismade with a perforated screw-stem, d, to be screwed into the journal orshaft-box, and in the upper end of the perforation of which is secured asmall tube, E, to receive the siphon-wick e, by which the oil is carriedto the journal to be lubricated. The upper end of the tube E extendsnearly to the bottom a of the reservoir A. In the bottom a of thereservoir A are secured two tubes, 13 O. The upper end of the tube 13rises nearly to the top of the reservoir A, and its lower end extendsdown into the distributing-chainber D so far as to be below the upperend of the tube E. The

upper end of the tube 0 rises a little above the bottom a of thereservoir A, so that any sediment that may be in the oil will settleupon the bottom of said reservoir and cannot flow through the tube 0into the distributing chamber D. The lower end of the tube 0 extendsdownnearly to the bottom of the distributing-chamber D.

The lower end of the tube 0 may be bent up into such a position that aplug may be inserted in it through the air hole or vent, F, formed inthe upper part of the side of the distributing-chamber D, to prevent theoil from flowing down through the tube 0 when the reservoir A is beingfilled.

With this construction the oil will llow down through the tube (J intothe distributingchmnber D until the lower end of the tube Bis covered,which will prevent the entrance of any more air into the reservoir A,and will stop the flow of the oil until enough oil has been carried outby the siphon-wick c to again uncover the lower end of the tubeB,andallow air to again pass up through the tube B. In this way the oilwill be kept at about the same level in the distributing-chamber D, sothat the siphon-wick may carry it out in a uniform quantity.

Air, to supply the place of the distributed oil, enters through the ventF.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent An improved oil-cup,formed of the reservoir A, provided with a bottom, a and a hollow stein,a closed with a serew-plug, G, the distributingchamber D, provided witha hollow screw-stem, d, and the air hole or vent F, and the three tubesE B 0, said parts being eonstructed and arranged to operate inconnection with each other, substantially as herein shown and described.
